Changing the filename of the cover image

[jiembe]

I like my cover image with a simple name like "cover.jpeg" but sometimes it as a weird name like "a000121etc.jpeg" as example. How can I change that filename? Changing it in the editor result with 2 files since Calibre reinsert the previous file as cover?

Where I'm I wrong or what I'm misunderstanding?

Calibre stores a copy of the cover in it's book folder, and that file is always called "cover.jpg".

If you run Polish on a book with the box checked to update the cover, it will copy that external file into the book, and you will have a "cover.jpg" in the book file. Ditto if you convert the book.

If you manually rename the cover image using the editor, and save the book, the old filename should be gone. So what are you doing then? At what point or with what action does Calibre revert to the original filename?

I try again and this time it works ! (But the original name was cover.jpg which I simply change to cover1.jpg). I will re-post my question when I stumble again on this specific problem, with an example. As for the filename of the image in calibre repertory it keeps the original name cover.jpg.
